Upper & Lower limb MCQs Q/A-3 41 to 60 Questions and Answers

👉41 A) Paired contraction of the FCU and ECU causes ulnar deviation of the wrist.
👉42 D) The internal intercostals are accessory muscles used during expiration. In addition to the other choices, the external intercostals and scalene muscles serve as accessory muscles during inspiration. Diaphragmatic muscle contraction (innervated by the phrenic nerve) serves as the primary muscle of respiration during inspiration.
👉43 D) The posterior cutaneous nerve of the thigh (S1–S3) is part of the sacral plexus.
👉44 C) The brachialis muscle is supplied mainly by the musculocutaneous nerve. A small branch of the radial nerve may sometimes innervate the lateral portion of this muscle. The brachialis muscle originates at the lower half of the anterior humerus and inserts at the ulnar tuberosity.
👉45 D) The radial nerve originates from the C5 through T1 nerve roots and the posterior cord (originates from upper, middle, and lower trunk

👉46 B) The semitendinosus is an internal rotator of the hip. All the other muscles are external rotators.

👉47 B) This injury usually occurs because of a lateral blow to the knee causing a rupture in the ACL,MCL, and medial meniscus. This occurs when a lateral force is applied to the knee when the foot is fixed to the ground causing a rotational force to tear all three structures.

👉48 C) Most sprains affect the anterior talofibular ligament. The ligament comes under strain and is vulnerable to injury, particularly when the foot is inverted.

👉49 B) The femoral nerve is formed from the L2 through L4 nerve roots. The main motor component innervates the iliopsoas (hip flexor) and the quadriceps (knee extensor).

👉50 C) The extensor digiti minimi muscle is innervated by the ulnar nerve. All of the other choices are muscles that are innervated by the radial nerve. Other muscles innervated by the radial nerve include the extensor carpi ulnaris, the extensor digitorum communis, and the extensor pollicis longus.

👉51 D) L4 is at the level of the iliac crests.

👉52 A) The genitofemoral nerve is part of the lumbar plexus (L1–L4). The sacral plexus also includes the posterior cutaneous nerve of the thigh.

👉53 D) The anconeus muscle originates at the lateral epicondyle of the humerus and inserts along the lateral side of the ulna. This muscle functions in forearm extension as well as stabilization of the elbow joint against flexion or pronation-supination. The anconeus muscle is innervated by the radial nerve.

👉54 A) There are six dorsal compartments to the wrist. The first compartment houses the APL and the EPB tendons. This is the location where De Quervain’s tenosynovitis can occur.

👉55 B) The gluteus maximus is an external rotator of the hip. All the other muscles are internal rotators.

👉56 B) The normal range of motion of the knee is 0° to 135°.

👉57 B) The deltoid ligament functions to support the medial surface of the ankle. It helps to connect the tibia to the calcaneus, navicular, and talus bones.

👉58 C) The tibial nerve is comprised of L4 through S3 nerve roots. In the popliteal fossa, the nerve branches off to the gastrocnemius, popliteus, soleus, and plantaris muscles. The nerve’s primary actions are foot inversion and ankle plantar flexion.

👉59 B) The FCU is innervated by the ulnar nerve. All of the other choices are muscles that are innervated by the median nerve. The median nerve also innervates the fl exor digitorum superficialis. The flexor digitorum profundus is dually innervated by the median (second and third digit) and the ulnar nerves (fourth and fifth digit).

👉60 D) The thyroid cartilage is located at the level of C4, C5 anteriorly.

Dr .Lalit Choudhary
Hii everyone, I'm Dr Lalit Choudhary PT. Born and brought up in delhi. Practicing as a professional PHYSIOTHERAPIST. As a therapist I love to interact with others and and get myself updated regarding all the social issues which are leading my countrymen to distress themselves. Yes, I agree that Iam a workaholic but my work gives me immense pleasure but there are sometimes when I feel stressed up so to relax myself I travel to new places, meet new people and try to adopt their culture. Most of the time I like to travel hills as it helps me to relax and enjoy our nature beauty. For being a good therapist and to deal with all the difficulties I always prefer to be good listener and have good patience that is what my strength is. I also work as a social worker and the Founder of thesocialphysiofitnessclub and PHYSIO FIT INDIA. In last I just want to say that " I believe that physical therapy is not just a therapy but actually a remedy which not only make you physically fit but also adds happiness, joy and more days to your life." So don't just sit and thought now it's time to stand and work on yourself.
